Comments Off on All-female high school team invents solar-powered tent for homeless

Twelve young women from San Fernando High School in California have created a solar-powered tent to serve the growing homeless population in the San Fernando Valley. Daniela Orozco and her classmates noticed the stunning increase in people living in the city, located 20 miles northwest of downtown Los Angeles . They wanted to act. “Because we come from low-income families ourselves, we can’t give them money,” Orozco  told Mashable . With the help of DIY Girls , the young women invented a solar-powered tent, which folds into a backpack, to serve the people struggling with homelessness in their community. Founded in 2012, DIY Girls began its work with 35 girls in an elementary school classroom. In 2016, it served 650 young female students from schools, elementary through high, all over Los Angeles County. Due to high demand made on the small organization, DIY Girls currently has a wait-list for its much-needed services. Only 27 percent of the STEM workforce is female, and only 6 percent of current female scientists are Hispanic or Latina. “When I was getting my [aerospace engineering] master’s degree, I was often the only girl in the class and definitely the only Latina in the class,” DIY Girls executive director Evelyn Gomez told Mashable . “It felt like kind of impostor syndrome.” Familiar with the challenges faced by young women of color, Gomez now serves as a guide for the next generation of female scientists and engineers .

If they encountered an issue in a code or circuit, they sought out resources online to solve the problem. “You’re learning new things you’ve never even heard of or even thought of,” Chelly Chavez, who learned the C++ programming language to refine the tent’s functionality, told Mashable. To further develop their work, the young women were awarded a $10,000 grant from the Lemelson-MIT Program. The team hopes that their accomplishments will inspire other young women to seize the scientific spirit. “[There are] only two junior girls in our AP Calculus class, which has way more guys than girls,” Paola Valtierra told Mashable, “But we’re gonna change that.” A post shared by DIY Girls InvenTeam (@diygirls_inventeam) on May 19, 2017 at 8:58pm PDT Via Mashable Images via DIY Girls

Richard Branson signs deal for India’s first super-speedy hyperloop route

Comments Off on Richard Branson signs deal for India’s first super-speedy hyperloop route

Travelers spend around three hours journeying from Mumbai to Pune by train today in India . A hyperloop could revolutionize the trip, slashing it down to a mere 25 minutes. And that’s exactly what Richard Branson -backed Virgin Hyperloop One aims to do. They signed an agreement with the state of Maharashtra, as the state announced their intention to construct what could be India’s first hyperloop route between Pune and Mumbai. Virgin Hyperloop One just signed an historic agreement with the Indian state Maharashtra. They plan to construct a hyperloop between Mumbai and Pune, a corridor 130,000 vehicles travel daily right now. They’ll begin with an operational demonstration track. Branson said in a statement , “I believe Virgin Hyperloop One could have the same impact upon India in the 21st century as trains did in the 20th century.” Related: Virgin Hyperloop One: Richard Branson invests in Musk-inspired high-speed transportation system 26 million people would be connected by the new route, which would link the two cities and Navi Mumbai International Airport. The electric transportation system would cut greenhouse gas emissions by as much as 150,000 tons a year. And a pre-feasibility study conducted by Virgin Hyperloop One revealed over 30 years the route could offer $55 billion in socio-economic benefits, as people save emissions and time. The hyperloop route would support 150 million passenger trips a year, according to Virgin Hyperloop One, saving more than 90 million hours. Devendra Fadnavis, Maharashtra chief minister, said the route would create tens of thousands of jobs in manufacturing, construction, service, and information technology. What comes after a signing? First, a six-month in-depth feasibility study. The study will scrutinize environmental impact, cost, funding models, regulations, and economic and commercial aspects. A procurement stage would follow to nail down a public-private partnership structure, and then construction would begin, with the demonstration track built in the first phase. According to Virgin Hyperloop One, the demonstration track could be built “in two to three years from the signing of the agreement,” and the second phase could see completion of the full route in five to seven years. + Virgin Hyperloop One + Virgin Images via Virgin Hyperloop One ( 1 , 2 )

Nova Scotia Power pioneers new energy storage system using Tesla Powerpacks

Comments Off on Nova Scotia Power pioneers new energy storage system using Tesla Powerpacks

Nova Scotia Power has established a pilot project that utilizes Tesla’s Powerpack 2 home batteries and their utility-grade Powerpack batteries to form an improved energy storage system for local wind power. Based in Elmsdale, the Intelligent Feed Project aims to bridge any gaps found in the electrical grid by installing Powerpacks where wind turbines are generating surplus energy. These batteries would allow power to be stored for later use, perhaps when there is a power outage or a windless day. While the Powerpack’s expansion into Nova Scotia isn’t quite as massive as its application in places like South Australia , this latest move demonstrates its potential to improve energy storage in power grids. The Elmsdale battery station will serve 300 homes, 10 of which will have Tesla Powerpack 2 batteries. Partially funded by the Canadian government, the trial program will begin at the end of February and will continue until 2019. The physical infrastructure of Powerpacks will remain even after the trial has ended. If the trial is successful, Nova Scotia Power may decide to offer additional programs to local communities. Related: Nantucket to be powered by a 48 MWh Tesla Powerpack system Simply bringing the Powerpacks into the homes and neighborhoods of Elmsdale seems to be having a positive impact on engagement in clean energy infrastructure. “The Powerwall, that was something I hadn’t heard about,” said homeowner Mark Candow . “I was definitely intrigued.” The ease-of-installation and the interactive app provided by Tesla are certainly selling points for consumers. “The ability to monitor their home usage is really making them think more about how they’re using electricity in their home,” said smart grid engineer Rob Boone , “and I think it’s going to make them more energy efficient .” Via Engadget Images via Nova Scotia Power

It is no wonder our kitchens have grown so big, we need all the space to store what the Unclutterer calls “unitaskers” , devices that do just one thing. And while removing the lids from recalcitrant jars can be tough, we have a dumb sheet of rubber in the drawer that does the job every time…. Read the full story on TreeHugger
